Re:Return path Problem w/ Modems


OBVIOUSLY AT LOWER FREQUENCIES THE LOSS WILL BE LESS THAN AT HIGHER. DEPENDING ON BRAND AND MODEL OF A 4 WAY SPLITTER, THE LOSS IS ABOUT 7. SO LETS SAY 6 AT 19MHZ UPSTREAM AND POSSIBLY 8DB ON THE DOWNSTREAM. BUT ANYONE WHO HAS BEEN IN CABLE FOR MORE THAN 1 DAY KNOW THAT YOU CAN NOT HAVE 45DB GOING INTO A 4 WAY AND 45 COMING OUT. A BARREL POSSIBLY.

>I dont think any questions are stupid. Anyone that comes to this forum and asks questions is a brother or a sister in cable and will likely be successful. On the other hand, folks that judge and insult come from a different place, who knows where they will end up.
>Saying a four way splitter has a 7 db loss is to broad of a statement. At what frequency are you speaking of? Do you know the loss of 19mhz?

>>YOU CAN NOT GET 45 IN AND 45 OUT OF A 4 WAY. 4 WAY HAS 7DB LOSS...ITS NOT THE BRAND OF THE SPLITTER, ITS HOW MANY PORTS. YOU ARE LOSING TOO MUCH SIGNAL DOWNSTREAM AND UPSTREAM ON AN 8 WAY. ITS PECKIN AT YOU BECAUSE YOUA RE STUPID

>>>I install a lot of cable modems. Have installed several kinds but the ones I'm havinf trouble with is the GI Surfboards. The cable modem is external and connects to an ethernet card.etc,etc,etc,
>>>the problem is that when it is hooked to a four way splitter or eight way the modem becomes unstable or works intermittingly. I use primarily Regal Gold 120db EMI or Tru Spec 120dB EMI. The modem would work fine thru a 2way or three way but 4's and 8's would kill it. The RF being sent back was 19MHz and it measured 45db before the 4 ways and 45 dB out of the four way input. This was very strange and have no explanation for it.Has anyone come across this before or know why this happens. It is easily gone around to get it going again but the WHY is peckin at me. help if ya can. Thanks
